Gregory Nutt efe65749ce Fix condition logic: The setup seems to support a network without sockets. That is not the case. 
Squashed commit of the following:

    sched/sched/sched_getsockets.c:  Fix an error in conditional compilation.
    fs/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    Documentation/:  Remove all references to CONFIG_NSOCKET_DESCRIPTORS == 0
    include/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    libs/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    net/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    sched/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    syscall/:  Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
    tools/:  Fixups for CONFIG_NSOCKET_DESCRIPTORS no longer used to disable sockets.

fs_procfs.c fs/procfs: Remove the unnecessary critical section 2018-11-29 12:51:34 -06:00
fs_procfscpuload.c procfs: Most stat() implementations were not initializating the st_atime, st_ctime, and st_mtime fields. 2017-02-15 09:59:09 -06:00
fs_procfscritmon.c Critical Section Monitor (sched/ and fs/procfs: Remove SCHED_IRQMONITOR_GETTIME to simplify the clock source selection: (1) Use up_critmon_gettime if SCHED_IRQMONITOR, (2) Call clock_systimespec if SCHED_TICKLESS, (3) Don't collect timing info for all other cases and move up_critmon_* to arch.h avoid the duplicated declaration. 2019-01-27 10:13:28 -06:00

fs/procfs README
================

  This is a tiny procfs file system that allows read-only access to a few
  attributes of a task or thread.  This tiny procfs fs file system can be
  built into the system by enabling:

    CONFIG_FS_PROCFS=y

  It can then be mounted from the NSH command like like:

    nsh> mount -t procfs /proc

Example
=======

  NuttShell (NSH) NuttX-6.31
  nsh> mount -t procfs /proc

  nsh> ls /proc
  /proc:
   0/
   1/

  nsh> ls /proc/1
  /proc/1:
   status
   cmdline

  nsh> cat /proc/1/status
  Name:       init
  Type:       Task
  State:      Running
  Priority:   100
  Scheduler:  SCHED_FIFO

  nsh> cat /proc/1/cmdline

  nsh> sleep 100 &
  sleep [2:100]
